Instructions

Roast the vegetables

Preheat oven to 425°F (220°C). Toss tomatoes, zucchini, carrots, and a drizzle of olive oil with salt, pepper, and half the minced garlic. Spread on a baking sheet and roast 18‑20 minutes, stirring once, until caramelized and tender.

Pro Tip: Use a hot sheet pan; the high heat creates a quick glaze.

Cook the pasta

While vegetables roast, bring a large pot of salted water to boil. Add pasta and cook 1‑2 minutes less than package instructions. Reserve 1 cup of cooking water, then drain.

Pro Tip: The starchy water will help emulsify the butter sauce.

Make the butter sauce

In a large skillet over medium heat, melt butter. Add the remaining garlic and sauté 30 seconds until fragrant. Deglaze with ¼ cup of the reserved pasta water, stirring to create a glossy emulsion.

Pro Tip: Keep the heat moderate to avoid browning the butter.

Combine pasta and vegetables

Add roasted vegetables to the butter skillet, then toss in the cooked pasta. Pour in another ½ cup of pasta water as needed, stirring until the sauce coats every strand and the mixture is glossy.

Pro Tip: Finish with a splash of lemon juice for brightness if desired.

Finish and serve

Remove from heat, stir in grated Parmesan, and season with extra salt and pepper. Sprinkle chopped basil or parsley, drizzle a tiny drizzle of olive oil if desired, and serve immediately.

Pro Tip: A pinch of red‑pepper flakes adds subtle heat.

Expert Tips

Tip #1: Roast on a single layer

Crowding the pan steams vegetables instead of caramelizing them. Use two sheets if needed, keeping each piece spaced.

Tip #2: Reserve pasta water

The starchy water binds butter and veggies, creating a silky sauce without cream.

Tip #3: Finish with fresh herbs

Add basil or parsley at the end to preserve their bright flavor and color.

Storage & Variations

Store leftovers in an airtight container for up to 3 days; reheat gently, adding a splash of water to revive the sauce. Swap butter for olive oil for a lighter version, or add protein such as grilled chicken, shrimp, or chickpeas for extra sustenance.

Frequently Asked Questions

Yes. Whole‑wheat pasta adds extra fiber and a nutty flavor. Cook it a minute longer than the package suggests to ensure a tender bite that still holds the sauce.

Substitute with an equal amount of olive oil or a mix of oil and a splash of cream. The sauce will be less rich but still flavorful; finish with extra Parmesan for depth.

Toss the drained pasta with a tablespoon of olive oil before adding it to the skillet. The reserved pasta water also creates a smooth coating that prevents clumping.
